The full lineup for the 2015 Jingle Ball series has finally arrived. Following the Los Angeles concert announcement, on Monday (Oct. 5), the short pop tour was announced in full. And to help usher in this year's holiday season, everyone from 5 Seconds of Summer to Selena Gomez to One Direction to Calvin Harris will be performing at the iHeartRadio series.

iHeartRadio rolled out the Jingle Ball lineups throughout the day on Monday, and every major market from Dallas (Dec. 1) to Tampa (Dec. 19) has a packed stack of musicians, as Entertainment Weekly.

The biggest shows seem to go to Dallas and Los Angeles, where One Direction will play two of what are sure to be very few shows in support of their new album Made in the A.M. Other major acts for Jingle Ball 2015 include The Weeknd (L.A., Boston, New York, Miami), Gomez (San Francisco, L.A., Philadelphia, New York, Chicago) and Demi Lovato (Dallas, San Francisco, Minneapolis, Boston, New York, Washington D.C., Miami, Tampa).

Other acts on the various bills include Ellie Goulding, Zedd, Charlie Puth, Natalie La Rose, Shawn Mendes, R. City and Joe Jonas' new band DNCE.
